Description
Technical field
The present invention relates to a kind of interior collector and include the collector of this interior collector and include the travelling-wave tube of this collector.
Background technology
Space travelling wave tube is the core devices of space communication, due to particular/special requirement and the unrepairable of space travelling wave tube of space application so that reliability becomes one of most important performance of travelling-wave tube.Space travelling wave tube main heat sink mode is heat loss through conduction, and high-power space travelling wave tube output is big, and heat consumption is high, and collector heat radiation pressure is big, and solving the type traveling-wave tube collector heat dissipation problem becomes the key issue improving its reliability.
In travelling-wave tube, collecting pole structure is generally made up of collector in metal outer collector, insulating porcelain piece, metal.Electronics note, through the high frequency interacting system of travelling-wave tube, surrenders portion of energy to traveling-wave field, and electromagnetic wave signal is amplified.The electronics note leaving high-frequency electric field still comprises sizable energy, utilizes depressed collector to continue to reclaim this part component, to improve the efficiency of travelling-wave tube.And remaining electron energy is converted into heat energy in collector, and it is transmitted to outside pipe by interior collector, insulating porcelain piece and outer collector.
Fig. 1 show the generalized section of existing collecting pole structure, wherein receive in collector as symmetric form, it includes interior collector 1, outer collector 3 and insulating porcelain piece 2, electronics inlet 4 on interior collector 1 is arranged in level mouth, and this electronics inlet 4 is perpendicular to electronics note incident direction and arranges.Fig. 2 show the profile after existing collector welds with base plate and collector upper cover, and wherein the bottom 5 of collector is for closely welding with base plate 7, and the collector first half 6 is for closely welding with collector upper cover 8.
Fig. 3 show the equipotential surface for existing collector and electron trajectory schematic diagram, wherein with A point-like electron and B point-like electron, existing collector trajectory of electron motion is described, in Fig. 3,1 notes approach axis to for electronics, and 2 enter electrode movement direction to for A point-like electron, and 3 to for A point-like electron direction of motion equipotential line radial component, 4 to for A point-like electron direction of motion equipotential line tangential component, 5 note Impact direction to for A point-like electron, and 6 enter electrode movement direction to for B point-like electron, and 7 to for B point-like electron Impact direction.
Electronics note enters after collector straight, and because the repulsion between electric charge is dispersed to surrounding, wherein the A point-like electron direction of motion as it is shown on figure 3, be decomposed into electric field equipotential line radial direction (namely 3 to) and tangential direction (namely 4 to) by the A point-like electron direction of motion；Under the effect of potential difference, A point-like electron is subject to equipotential line power radially upward, and under this power effect, A point-like electron reduces along equipotential line radial direction movement velocity, and its direction of motion is increasingly partial to left side, until it reaches on collector inwall.B point-like electron is electronics on collector axis, and the direction of motion overlaps with equipotential line radial direction, and the motion of B point-like electron does not deviate, and directly slows down and beats on collector bottom.With B point-like electron for demarcation line, the electronics in left side is beaten in left side, and the electronics on right side is beaten on right side.Symmetry due to electronics note and collector, it is substantially impartial that electronics beats the quantity in collector all directions, collector is respectively also impartial to the heat produced, therefore quantity that electronics is beaten in interior collector 1 all directions is substantially impartial, due in use, the bottom 5 of collector is for closely welding with base plate, a part of heat energy in collector is directly conducted to base plate and dispels the heat, and another part heat energy is passed through to be transmitted to the lower half 5 of collector by the collector first half 6, conduct again to base plate and dispel the heat, heat consumption on collector is more big, the top 6 of collector is more big with the temperature difference of the bottom 5 of collector, in turn result in dispel the heat up and down uneven.
Accordingly, it would be desirable to design a kind of under the premise not changing electrical property, can make the electric current that collector is collected more beat near base plate position, the collector of collector radiating effect can be greatly improved.
